Our system only allows for one promotional or voucher code to be used per order. If you also want to use a gift voucher on the same order, we suggest completing your order with the promotional code. Once placed the order, contact our customer service team with the following information:
1. The order number.
2. The gift voucher code(s) you wanted to use.
We will disable the gift voucher(s) and refund the amount on the bank account you used to pay for your order. You will receive a confirmation when this is done.
Please note: It is not possible to combine multiple promotional codes in one order. We make a clear distinction between gift vouchers and our general promotion deals. We are unable to offer you this same procedure for the latter. Thank you for understanding.
